Echinocereus schmollii typically grows solitary with cylindrical, purple to blackish shoots up to long and in diameter. The roots are slightly thickened. The plant has nine to ten rounded, tuberculated ribs and up to 35 pink hair-like thorns that create a woolly appearance, which turn white or darker and can be up to long.
The bright pink, funnel-shaped flowers appear near the tips of the shoots, measuring long and up to in diameter. The juicy, egg-shaped to spherical fruits are slightly purple-green.[2]
Echinocereus schmollii is found in the Mexican state of Querétaro growing in the Chihuahuan Desert at elevations around . It is found growing along with Astrophytum caput-medusae.[3]
First described as Cereus schmollii in 1931 by Wilhelm Weingart, the specific epithet honors German artist and cactus collector Ferdinand Schmoll. Nigel Paul Taylor reclassified it to the genus Echinocereus in 1985.[4]
